For a circle with a diameter of 7 inches, several key properties can be calculated. The radius, which is half the diameter, equals 3.5 inches. The circumference, or the distance around the circle, is determined using the formula Circumference=π×Diameter. Substituting 7 for the diameter, the circumference is approximately 21.99 inches
To find the area, the formula Area=π×Radius2\ is used. With a radius of 3.5 inches, the area is about 38.48 square inches. These calculations help define the circle’s size and dimensions based on its diameter.
